If you’re playing Arc Raiders, you’ll often find that quests aren’t just about shooting and collecting loot—they usually involve exploring, investigating, and understanding how the game world works. One quest that many players come across is “Source of the Contamination”, given by Celeste after completing Water Troubles. In this guide, I’ll walk through how this quest works in practice, common pitfalls, and tips that most players find helpful.
What Is the “Source of the Contamination” Quest?
In general, this quest is about investigating a potential issue with the water supply at the Dam Battlegrounds. Celeste, the trader who gives the quest, frames it as a public safety concern, but in practical terms, it’s an exploration and collection quest with a few combat encounters along the way.
Once you accept it, your main tasks are:
Most players treat this as a mid-tier quest—nothing extremely difficult, but it requires some navigation and attention to detail.
Where Do I Start, and How Do I Navigate the Dam?
When you first enter the Dam Battlegrounds, most players head straight for the Water Treatment Building. It’s generally the easiest landmark to locate and serves as your starting point for finding the Flood Spill Intake.
In practice:
Navigation is straightforward once you know these patterns. Most players report that taking your time to check each object carefully helps avoid missing key components.
What Does “Investigate Suspicious Objects” Actually Mean?
In general gameplay, “investigating” usually involves interacting with a highlighted object and sometimes clearing a small area of enemies. For this quest:
A practical tip: check the surrounding area carefully. These objects are sometimes hidden behind natural elements like trees or low walls.
How Difficult Is Collecting Materials for This Quest?
The quest requires:
In general, these materials are easy to find if you explore thoroughly. Steel Springs and Duct Tape are usually scattered around the Dam and swamp areas. The Mod Component can sometimes be in a slightly less obvious spot, but most players find it near machinery or control panels.
If you’re running low on components, you may notice that cheap arc raiders items are available through normal gameplay, and acquiring a few of them can save you from repeated farming. In practice, it’s rare to run into shortages if you check containers and breakable objects along your path.
Are There Combat Challenges During This Quest?
Most of the time, this quest doesn’t involve heavy combat. You may encounter occasional enemies near the intake or suspicious objects, but they are usually standard AI units rather than mini-bosses.
In practice:
This quest is less about fighting skill and more about observation and planning your route.
What Happens After You Complete the Quest?
Once you investigate the contamination and collect all required materials, you return to Celeste. The dialogue usually reflects concern about the severity of the contamination, and most players note that it has a slightly darker tone than other quests.
Rewards are standard for a mid-tier quest: some crafting materials, experience points, and occasionally new blueprints. This makes the quest useful for progression, but it’s not a grind-heavy challenge.
Common Mistakes Most Players Make
In practice, slowing down and planning your route makes the quest feel smoother and less repetitive.
Practical Tips for Efficient Completion
The Source of the Contamination quest is a good example of how Arc Raiders blends exploration, collection, and light combat. Most players find it straightforward once they understand the landmarks, know what suspicious objects to check, and gather required materials along the way. Paying attention to the environment and planning your path is usually the key to completing it efficiently.
This quest also shows how the game mixes narrative with gameplay: the dialogue emphasizes urgency and concern, but the mechanics are simple and predictable once you know what to look for.

In general, this quest is about investigating a potential issue with the water supply at the Dam Battlegrounds. Celeste, the trader who gives the quest, frames it as a public safety concern, but in practical terms, it’s an exploration and collection quest with a few combat encounters along the way.
Once you accept it, your main tasks are:
- Reach the Water Treatment Building in the Dam.
- Search for the Flood Spill Intake near the swamp.
- Investigate any suspicious objects you find.
- Collect a few crafting components: 5x Steel Spring, 5x Duct Tape, and 1x Mod Component.
Most players treat this as a mid-tier quest—nothing extremely difficult, but it requires some navigation and attention to detail.
Where Do I Start, and How Do I Navigate the Dam?
When you first enter the Dam Battlegrounds, most players head straight for the Water Treatment Building. It’s generally the easiest landmark to locate and serves as your starting point for finding the Flood Spill Intake.
In practice:
- Stick to the main paths. Many players try to shortcut through the swamp, but it’s easy to get ambushed or slowed down by environmental hazards.
- Pay attention to small visual cues. The intake itself is near the swamp, and there are usually pipes or metal structures that hint at its location.
- If you’re in a team, splitting tasks works well—one player can scout the intake, another can check nearby suspicious objects.
Navigation is straightforward once you know these patterns. Most players report that taking your time to check each object carefully helps avoid missing key components.
What Does “Investigate Suspicious Objects” Actually Mean?
In general gameplay, “investigating” usually involves interacting with a highlighted object and sometimes clearing a small area of enemies. For this quest:
- Suspicious objects are typically small devices, broken pipes, or unusual debris near the water supply.
- When you interact with them, the game usually prompts you with a short animation and adds the object to your quest log.
- Most players make the mistake of rushing this step. If you miss even one object, the quest may not progress, and you’ll have to backtrack.
A practical tip: check the surrounding area carefully. These objects are sometimes hidden behind natural elements like trees or low walls.

- 5x Steel Spring
- 5x Duct Tape
- 1x Mod Component

Are There Combat Challenges During This Quest?
Most of the time, this quest doesn’t involve heavy combat. You may encounter occasional enemies near the intake or suspicious objects, but they are usually standard AI units rather than mini-bosses.
In practice:
- Stick to cover when approaching the swamp area. Even a small group of enemies can overwhelm unprepared players.
- If you’re playing solo, consider engaging enemies one at a time rather than rushing in.
- Players in teams often find that having one person provide overwatch while another investigates objects speeds up the process.
This quest is less about fighting skill and more about observation and planning your route.
What Happens After You Complete the Quest?
Once you investigate the contamination and collect all required materials, you return to Celeste. The dialogue usually reflects concern about the severity of the contamination, and most players note that it has a slightly darker tone than other quests.
Rewards are standard for a mid-tier quest: some crafting materials, experience points, and occasionally new blueprints. This makes the quest useful for progression, but it’s not a grind-heavy challenge.
Common Mistakes Most Players Make
- Rushing through the swamp: It’s easy to miss the Flood Spill Intake if you don’t approach carefully.
- Skipping suspicious objects: Missing even one prevents quest completion.
- Ignoring materials along the way: Steel Springs and Duct Tape are easy to grab while exploring.
- Assuming heavy combat: Players often over-prepare for fights, but this quest is mostly about exploration.
- Backtracking unnecessarily: Knowing the landmarks (Water Treatment Building and Flood Spill Intake) saves time and frustration.
In practice, slowing down and planning your route makes the quest feel smoother and less repetitive.
Practical Tips for Efficient Completion
- Map your path from the Dam entrance to the Water Treatment Building, then to the swamp. This prevents wasted running around.
- Collect materials as you go, so you don’t need to backtrack after finding suspicious objects.
- If you play in a group, assign roles: one player gathers materials, one investigates objects, and another handles enemies.
- Pay attention to visual cues in the environment—they’re often subtle but reliable indicators for the intake and suspicious objects.
